OpenLensFlare: an open-source, lens flare designing and rendering framework

Lens flare rendering in computer games has always been lacking. While physically motivated solutions based on real camera systems exist, their inherent complexity makes them inappropriate for widespread use. Developers are not trained to work with these complicated imaging systems, an...

CoUIM: crossover user interface model for inclusive computing

Persons with disabilities can face considerable challenges accessing many computing systems, such as cloud computing. We created six low-cost user interfaces using: keyboard-based, touchable, speech-based, touch-less gesture, tactile, and then combined them all in one user interface termed Crossover U...

Extraction of sliding collision area of knee-form for automobile safety inspections

The United Nations Economic Commission for Europe defines a safety regulation based on the possible collision between the driver’s knee and an automobile’s interior parts. The “knee-form” apparatus is used to evaluate compliance with this regulation. Current software for analyzing possible c...

Improving the ergonomics of hand tracking inputs to VR HMD’s

This study improves the ergonomics of using the Leap Motion hand tracking device with an Oculus Rift. The improvements were realised through the use of a 3D printed mount that angled the Leap Motion down by 30 degrees. This allowed for users to interact with a virtua...

MAELab: a framework to automatize landmark estimation

In biology, the morphometric analysis is widely used to analyze the inter-organisms variations. It allows to classify and to determine the evolution of an organism’s family. The morphometric methods consider features such as shape, structure, color, or size of the studied objects. In&#x...

fastGCVM: a fast algorithm for the computation of the discrete generalized cramér-von mises distance

Comparing two random vectors by calculating a distance measure between the underlying probability density functions is a key ingredient in many applications, especially in the domain of image processing. For this purpose, the recently introduced generalized Cramér-von Mises distance is an in...

Screen-space ambient occlusion for light field displays

In this paper, we discuss the challenge of generating the screen-space ambient occlusion (SSAO) visual effect on the state-of-the-art HoloVizio light field display. We detail the main features of modern SSAO techniques that are currently being applied during visualization on conventional 2D&...

CUDA-based SeqSLAM for real-time place recognition

Vehicle localization is a fundamental issue in autonomous navigation that has been extensively studied by the Robotics community. An important paradigm for vehicle localization is based on visual place recognition which relies on learning a database, then consecutively trying to find matchin...

Volume estimation of biomedical objects described by multiple sets of non-trimmed Bézier triangles

Estimating the volume of a 3D model of an object is an actual task in many scientific and engineering fields (for example, CAD systems, biomedical engineering tasks etc.). Spline surfaces is one of the most powerful and flexible methods used to describe a 3D model. At...

Parameterization of unorganized cylindrical point clouds for least squares B-spline surface fitting

In this study, a method for parameterizing unorganized cylindrical point clouds is suggested. The proposed method creates an initial base surface onto which points are projected to estimate parameter values for each point. To produce an initial base surface, we suggest the concept ...


Anisotropic octrees: a tool for fast normals estimation on unorganized point clouds

With the recent advances in remote sensing of objects and environments, point cloud processing has become a major field of study. Three-dimensional point cloud collected with remote sensing instruments may be very large, containing up to several tens of billions of points. This imp...

Unlimited object instancing in real-time

In this paper, we propose a novel approach to efficient rendering of an unlimited number of 3D objects in real-time. We present a rendering pipeline that is based on a new computer graphics programming paradigm implementing a holistic approach to the virtual scene definition. ...

Automatic plant recognition system for challenging natural plant species

Photosynthesis is one of turning points to shape the world. Plants use this process to convert light energy into chemical energy. Some of the early microorganisms evolved a way to use the energy from sunlight to make sugar out of simpler molecules, but unlike green plants...

Line segment similarity criterion for vector images

Vector representation of the images, maps, schematics and other information is widely used, and in computer processing of these data, comparison and similarity evaluation of two sets of line segments is often necessary. Various techniques are already in use, but these mostly rely o...

Application of vision-based particle filter and visual odometry for UAV localization

Conventional UAV (abbr. Unmanned Air Vehicle) auto-pilot systems uses GPS signal for navigation. While the GPS signal is lost, jammed or the UAV is navigating in GPS-denied environment conventional autopilot systems fail to navigate safely. UAV should estimate it’s own position without ...

Using genetic algorithms to estimate local shape parameters of RBFs

Estimation of design rainfall in unobservable places is important in hydrological engineering. The aim of this paper is to use genetic algorithms to find the optimal global and local shape parameters of radial basis functions (RBFs) to create an interpolation model to estimate scal...
